Answer:
Two sleeping bags, a tent, and the cooler.
Explanation:
To answer this question we need to understand what the sentence fragment is.
<u>Fragment sentence</u> is an incomplete sentence that can be a piece of a complete one, it doesn't have the whole idea or complete thought. Fragments are missing one of three main elements: a subject, a verb, or a complete thought.
<u>From the given options only this sentence is a fragment - Two sleeping bags, a tent, and the cooler.</u>
Because it doesn't have a complete thought, we can't understand what is happening to these items or who uses them or why they are mentioned at all. It is just a list of items and we don't get the full information.
All other options are complete sentences. They have a subject, a verb, and other modifiers.
I hope it helped you :)
